DOUBLE-BARRELED BREECH-LOADING FIREARM.

SIECIFICATION forming part of Letters Patent No. 790,293, dated May 23, 1905. Application filed September 26, 1904. Serial No. 225,868.

To rtZZ whom it may concern:

Be it known that I, Or'ro ANDREAS FLooKnN, a citizen of Germany, residing in the city of Mexico, in the Federal District and Republic of Mexico, have invented certain new and useful Improvements in Double- Barreled Breech-Loading Firearms, of which the following is a specification.

This invention relates to improvements in double-barreled breech-loadingfirearms; and it consists particularly in mechanism by means of which if both barrels are loaded and a cartridge in one of the barrels is discharged that barrel alone need be opened, the empty cartridge extracted, a new one inserted, and the breech closed, all without opening the other barrel. .The means by which this is accomplished is explained in the following specification and accompanying drawings.

For purpose of illustration a gun is shown having one barrel of small caliber, rifled, and the other barrel of larger caliber,smoothbore, and suitable for shot-cartridges; but the respective caliber of the barrels is immaterial.

Figure 1 is a side view of the central portion of the firearm; Fig. 2, a vertical section of the breech-block and cartridge-loading mechanism of one barrel closed; Fig. 3, a portion of the same mechanism shownin Fig. 2 with the breech-block raised and about to be pushed back; Fig. 4, the same mechanism shown in Fig. 2 when open and the cartridge in position for loading; Fig. 5, a cross-section of the breech and loading mechanism at line 0 of Fig. 2; Fig. 6, a plan of the bottom of a breech-block; Fig. 7, a view of the inside of the farther side wall of the metal box or case containing the lock, breech, and cartridge mechanisms; Fig. 8, a side view of the partition which divides said case vertically; Fig. 9, a view of the firing-pin; Fig. 10, a sectional plan of the firing-pin and lockingbolt mechanism viewed from below.

The same numeral refers to the same part throughout the several views.

In the drawings, 1 is a handle or grip partly surrounding and sliding on the magazines 2. To each side of this grip is attached an actionslide 3 and 3, which extends backward into the mechanism-case t. At the rear end of slide 3 and 3 is a diagonal slot 5 and 5, Fig. 8, which engages the outward ends of the transverse bolts 6 and 6. These bolts havea lateral movement between the sides of the case 4 and the partition 7 to the extent that when the outer end of either bolt is engaged in slot 5 its inner end is out of and clear of hole 8' in the partition 7, or if thrust in the opposite direction its outer end is clear of slot 5 and its inner end enters the hole 8 in partition 7. This lateral movement of each bolt is caused by the peculiar form of the firingpin 8, which on its lower side is provided with a square flange 9, which in its central portion 10 is constructed at an oblique angle to the axis of said pin. This flange engages in a correspondingly-shaped groove or channel in the upper side of the bolt, and consequentl y when the pin of the right-hand barrel, for example, is forced forward by the pressure of the hammer 12 the flange traverses said groove, and the oblique portion of the flange pushes the bolt 6 to the right and causes the outer end of the bolt to enter slot 5 in the right-hand action-slide 3, and at the same time the point of the firing-pin strikes the cartridge, causing it to explode. Now in order to reload this same barrel the grip 1 is drawn back, thus forcing back the bolt 6, the outer end of which is engaged in slot 5' and the inner end of which is clear of the hole 8 in the partition 7. This bolt passes transversely through the breech-block 13 and holds it in place. As the action-slide moves backward the bolt, following the line of least resistance, moves upward in the diagonal slot 5', thus lifting the forward end of said block across the rear of the barrel, Fig. 8. The cartridge-extractors 14:, one on each side of the breech-block, rise in a recess 15 in the wall of the barrel on each side and engage the rim of the cartridge. The rearward pressure of the action-slide continuing, the hammer 12 is forced backward by the pressure of the breech-block, which then slides back over the hammer, Fig. 1. The lever 16 lifts the cartridge-carrier 17, bringing up a fresh cartridge, which pushes the old cartridge up and out and comes opposite the barrel ready to be inserted. Then by reversing the operation of the grip 1 the action-slide draws the bolt 6 forward and downward, pulls forward the breech-block, presses in the new cartridge, and closes the breech-block. In order to guide the breechblocks and hold them in place, a pin 18 is secured at each end in the Walls of the case 4 and passes through the partition 7 and both blocks. Each block is constructed with a horizontal guide-slot 19, which allows the block to move freely back and forth, though held down by the pin 18. IVhen the block 13 has returned to the closed position, Fig. 2, the hammer still remains drawn back at full cock, Fig. 4, the spring 19 on firing-pin 8 presses said pin backward, the flange traverses backward the groove in bolt 6' and causes the bolt to move to the left, thus being disengaged from slot 5 in the right-hand action-slide 3 and entering hole 8 in the partition, Fig. 5. This locks the block in the closed position and sets free the action-slide on that side. It is obvious that the same operation can be performed With the lefthand barrel in the manner described. Consequently if both barrels are empty the bolts 6 and 6 engage the action-slide on each side, and both breech-blocks can be opened and the barrels loaded in one action; but if one barrel is empty and the other loaded the empty barrel may be opened and reloaded Without opening the loaded barrel. This system is applicable to all double-barreled breech-loading arms in Which the breech-opening mechanism is actuated by a grip and action-slide similar to that above described.

I make no claim to the form of cartridge carrier, extractor, magazine, or lock as described; but

IVhat I claim as of my invention, and desire to secure by Letters Patent, is-

1. In a double-barreled,breech-loading firearm, a separate breech-block and firing mechanism for each barrel, an operating device for simultaneously moving both breech-blocks to open the barrels, said operating device being normally disconnected from both breechblocks, and means for connecting said operating device with the block of either barrel operated by the firing mechanism of such barrel, as it is moved to discharge the same, to permit such barrel to be opened thereafter Without opening the other barrel,substantially as described.

2. In adouble-barreled,breech-loading firearm, a separate breechblock and firing-pin for each barrel, an operating device for simultaneously moving both breech-blocks to open the barrels, said operating device being normally disconnected from both breech-blocks, and means for connecting said operating device With the block of either barrel operated by the firing-pin of such barrel, as it is moved to discharge the same, to permit such barrel to be opened thereafter Without opening the other barrel, substantially as described.

3. In a double-barreled, breech-loading firearm, a separate breech-block and firing mechanism for each barrel, an operating device for simultaneously moving both breech-blocks to open barrels, said operating device being normally disconnected from both breech-blocks, means for locking both blocks in their closed position and means for connecting said operating device with the block of either barrel, and for simultaneously unlockingsuch block, operated by the corresponding firing mechanism of such barrel as it is moved to discharge the same to permit such barrel to be opened thereafter Without opening the other barrel, substantially as described.

4. In adouble-barreled,breech-loading firearm,aseparate breech-block and ii ring-pin for each barrel, an operating device for simultaneously moving both breech-blocks to open the barrels, said operating device being normally disconnected from both breech-blocks, a transversely-disposed longitudinally-movable bolt in each block, each bolt normally locking its block in the closed position, and a projection on each firing-pin for moving its corresponding bolt to unlock its block and connect it to said operating device as the pin is moved to discharge its corresponding barrel. substantially as described.

5. In a breech-loading double-barreled firearm, the combination, for each barrel, of a firing-pin having an inferior diagonal flange, a transverse bolt engaged by said flange, a vertical longitudinal partition in the center of the mechanism-case provided with a hole for engaging said bolt, and an action-slide provided with a slot for engaging said bolt, all adapted to lock or unlock the respective breech-blocks,

substantially as described.
